Laparoscopic partial adrenalectomy.

Abstract

Most laparoscopic adrenalectomies involve total removal of the whole adrenal gland, and reports of laparoscopic partial adrenalectomies have been very few. The criteria for performing a laparoscopic partial adrenalectomy have not been described. (a) Patients with functioning adrenal tumors smaller than 3 cm in diameter were selected. (b) The solitary adrenal tumors were evaluated by preoperative thin-slice computed tomography (CT) scan. (c) Solitary lesions were reconfirmed with intraoperative ultrasonography. (d) Partial adrenalectomy was performed with at least a 5-mm margin using a vascular stapler. Laparoscopic partial adrenalectomy was performed in five patients using the vascular stapler. Hemostasis was perfect in all five patients. The tumor was located in the inferior part of the right adrenal gland in three cases and in the upper pole of the left adrenal gland in two cases. The postoperation pathologic diagnosis was adrenocortical adenoma in all five patients, and excessive hormonal levels or symptoms all disappeared. Laparoscopic partial adrenalectomy can be performed safely using a vascular stapler.
